Final Project: Bank Account Simulator

Advanced Java — Final Project: Bank Account Simulator

Final Project — You've made it to the end!

🏦 Bank Account Simulator

This is your capstone project — bring together OOP, exception handling, collections, and generics to build a real-world banking simulation.

Concepts You'll Use

Classes & objects (BankAccount)
Custom exceptions (InsufficientFundsException)
ArrayList to store transaction history
Try/catch for safe withdrawals
String formatting for currency output

YOUR TASK

Build a BankAccount class with:

Fields: owner (String), balance (double), transactions (ArrayList)
Constructor that sets owner and initial balance
deposit(double amount) — adds to balance, logs transaction
withdraw(double amount) — subtracts from balance, throws InsufficientFundsException if balance insufficient, logs transaction
printStatement() — prints owner, balance, and all transactions

Then in main: create an account for "Alice" with $1000, deposit $500, withdraw $200, attempt to withdraw $2000 (should catch exception), then print the statement.

Need a hint?

Transaction log: use transactions.add("Deposit: +$" + amount);

Check: if (amount > balance) throw new InsufficientFundsException(...);

Format currency: String.format("$%.2f", balance)

Final balance should be: $1000 + $500 - $200 = $1300.00

Expected Output:

Error: Insufficient funds
--- Statement for Alice ---
Balance: $1300.00
Transactions:
Deposit: +$500.0
Withdrawal: -$200.0
